l 4 Claims. (Cl. 57-89) This invention relates to textile machines and particularly to twisting machines in which the spindles are pivotally mounted for swinging movement into and out of contact relative to a I 5 driving belt adapted to engage the whirls on said spindles.

An object of the invention is to provide a simple, inexpensive and easily actuated member to move a spindle away from its driving belt where the spindle may be retainedininoperative position and to permit return movement thereof by means of a spring when the member is returned to its initial position.

Another-object of the invention is to form the spindle actuating member or lever from aheavy rod or wire bent into shape and pivotally supported in aportion of the spindle supporting bracket. l

And finally it is an object of the invention to provide a simple locking means to retain the actuating member against removal from its position within the spindle bracket.l I A With the above and other objects in view the invention includes the features of construction and operation set forth in the following specication and illustrated in the accompanying draw- In the accompanying drawing annexed hereto and forming a part of this speciiication, I have shown the invention embodied in swinging spindle unit for an enclosed spindle type twisting machine but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as dening or limiting the scope of the invention, the claims appended to this specication being relied upo for that purpose.

In the drawing:

Fig. 1 is a front elevation of a complete spindle 40 unit, parts of the spindle, bobbin and its enclosure being broken away; and f Fig. 2 is a plan view of the spindle bracket and the pivotally mounted spindle unit shown in Fig. l, a part being shown in section to more clearly show the construction.

In the above mentioned drawing there has been shown but one embodiment of the invention which is now deemed preferable, but it is to be understood that changes and modications may be made within the scope of the appended claims without departing from the spirit of the invention.

. Briefly, and in its preferred aspect, the invention may include the following principal parts:

ilrst, a fixed bracket; second, a pivotally mounted bolster bracket thereon; third, a spindle unit rotatably mounted within said bolster bracket;

fourth, a bent wire lever hinged in a vertical axis within the xed bracket 'and having an intermediate portion adapted to engage the pivotally 5 mounted bolster bracket; and fth, a small wire wrapped around a reduced diameter of the lever formed near the end of the portion forming the pivot for the lever, the ends of the small wire engaging over 'portions of the xed bracket and 10 bolster bracket to retain the lever against accidental withdrawal.

Referring more in detail to the gures of the I drawing there is shown a bracket I0 secured in ilxed position to a portion of the machine frame l5 shown in dotted outline. This bracket I0 is provided withV an upwardly and laterally extending arm II through which extends a xed pin I2 forming the pivot upon which a bolster bracket I3 and spindle unit may be mounted for oscilla- 20 tion. On bracket I3 is mounted a bolster I4 and spindle unit the-whirl of which is shown at I5.

In the embodiment of the invention shown in the drawing the spindle unitmay haveits blade I6 enclosed by an inverted cup I1 secured at its 25 periphery to a mounting I8 therefore fixed to the bolster bracket I3. A helical spring I9 surrounding the lower end of the pin I2 serves to normally force the spindle unit on the bracket I3 in a direction to contact its whirl I5 with a driving belt 30 2li shown in dotted outline only in Fig. 1.

The above constitutes a standard construction for twisting machines'and per se forms no part of the present invention. To move the spindle unit on the bracket I3 away from the driving belt 20 35 and retain it in inoperative position a lever or detent 2| is provided preferably made from a heavy metal rod or wire and bent as will be best seen in the drawing. At one end the wire or rod from which the lever 2| ir formed enters a vertical hole 40 formed in the xed bracket Ill, this portion 22 forming the pivot upon which the lever 2I swings. Intermediate its ends the rod or wire 2l has an angularly disposed portion 23 adapted to bear against a side of the'bracket I3. The lever ZI 45 is extended downward and forms at its lowermost end a handle portion 24 by means of which the lever 2| may be moved to a position holding the bracket I3 with the spindle whirl out of contact with the belt 20. ,In this position of the lever 2| 60 the spindle unit is retained in its inoperative position until the lever is moved back to its initial position. As soon as the lever 2I has been moved spring I9 forces the spindle toward the belt so that the-whirl I5 will engage against the belt 2li.

1. A swinging spindle unit for textile machines comprising in combination, a xed bracket, a spindle unit supporting bracket pivotally mounted thereon, a lever pivotally supported within said iixed bracket and having an intermediate portion engaging and retaining said spindle unit in inoperative position when said lever is in one position, said lever being extended downward to form an operating handle therefor.

2. A swinging spindle unit for textile machines comprising in combination, a xed bracket, a spindle unit supporting bracket pivotally mounted thereon, a lever formed from a metal rod bent into shape pivotally mounted at one end to said straighten portions of the loop therein fit 4 aimera iixed bracket, an intermediate portion of said 1ever engaging and retaining said spindle unit in inoperative position when said lever is moved to one position, and spring means to permit said spindle unit to move to its operative position when said lever is moved to another position.,

3. A swinging spindle unit for textile machines comprising in combination, a 'iixed bracket, a spindle unit supporting bracket pivotally mounted thereon, a bent metal rod forming a lever pivotally mounted at one end to said ilxed bracket, an intermediate portion oi said lever engaging and retaining said spindle unit in inoperative position when said lever is moved to one position, a handle portion formed upon the opposite end of said rod, and means to retain said lever within said iixed bracket. p y

4. A swinging spindle unit for textile machines comprising in combination, a fixed bracket, a spindle unit supporting bracket pivotally mounted thereon, a bent metal rod forming a lever pivotally mounted at one end to said fixed bracket, an intermediate portion of said lever engaging and retaining said spindle unit in inoperative position when said lever is moved to one position, a. handle portion formed upon the opposite end of said rod, and a looped wire engaging a reduced diameter portion of said lever at the pivoted end thereof, whereby said lever is retained in position on the iixed bracket.
